Want to buy my first and last FAL: What to buy? Enterprise, DSA or CAI? Help please?

US Navy Petty Officer here wanting to buy a FAL. Very familiar with AK and AR systems but very little knowledge on the FAL platform.
Looking for a rifle that will not let me down. I'm a heavy shooter and this rifle WILL HAVE ROUNDS through it... Please give me your opinions.

IMBEL is a licensed producer of the FAL rifle, they have the benefit of the original FN factory blueprints, tooling package, etc. Very good receivers, banned from import to build new rifles on so they are hard to find and pricey. The DSA rifle is built on a DSA receiver, using a parts kit that used to be a used IMBEL produced rifle before it was cut up. Most of the other DSA rifles are made from new old stock STEYR produced parts and new DSA produced parts.

DSA bought the blueprints and tooling and spare parts from Steyr in Austria (another FN licensee) but are not licensees. Most of their early rifles were made from NOS STEYR parts and as their stocks got depleted they gradually started making the parts here. Nowdays most of the parts in them are DSA made.

Entreprise and CAI reverse engineered their receivers, AFAIK they have no factory blueprints or anything to work from. Consequently they have "issues" when building on them. Entreprise is the better of the two, CAI has such a bad rep that resale value is lower. These guns are all made from parts kits put on their receivers with enough USA made parts to be comlpiant.

DSA or Imbel or Enterprise in that order. With an Imbel you need 1 more US made part (need 7 total for 922R compliance). Metric instead of inch (more mags are available). Even if you shoot alot I think a standard barrel is best all around.If you want a carbine 18" is the shortest I would go.
Keep an eye on Fal files or gunbroker. Stay away from the century crap. Unless its an imbel reciever and you can test it out otherwise buyer beware.
